What are the categories of hurricanes?

The indomitable force of hurricanes is a constant reminder of the vastness and power of nature. In this ever-changing world, where weather events can impact our lives in a matter of hours, understanding hurricane categories is vital. 

Throughout this article, we will explore in detail each aspect of the hurricane categories. From how its intensity is measured to how each category is prepared and why it is essential to anticipate its arrival.

Hurricane Category Scale

When it comes to understanding the intensity and potential danger of a hurricane, the Category Scale is an essential tool. This scale, known as the Saffir-Simpson Scale, was developed by engineer Herbert Saffir and meteorologist Robert Simpson in the 1970s. 

Its purpose is to provide a clear and concise way to classify the strength of a hurricane based on wind speed and the potential damage it can cause.

The scale consists of five categories, numbered from 1 to 5. Each category is defined by a specific range of wind speed, which increases as we go from category 1 to 5. Let's look at an overview of each category:

Category 1: Winds 74-95 mph (119-153 km/h)

Hurricanes in this category have moderate winds that can cause superficial damage. Trees and small branches are often downed, and homes can suffer minor roof and window damage.

Category 2: Winds of 96-110 mph (154-177 km/h)

Winds in this category increase in intensity. Damage is more extensive, with larger trees downed and significant damage to roofs and windows. Coastal flooding is also possible due to increased surge.

Category 3: Winds of 111-129 mph (178-208 km/h)

In this category, hurricanes are considered "major." Damage is more severe, with uprooted trees and extensive damage to buildings. Coastal flooding is a major concern due to the combination of high winds and high tides.

Category 4: Winds of 130-156 mph (209-251 km/h)

Category 4 hurricanes are extremely dangerous. Damage is catastrophic, with most trees downed and most homes sustaining severe damage. Flooding is widespread and may require mass evacuations.

Category 5: Winds greater than 157 mph (252 km/h)

The highest intensity on the scale, Category 5 hurricanes, cause absolutely devastating damage. The winds uproot trees, destroy homes and buildings, and cause widespread flooding. Recovery can take years.

It is essential to understand that the Hurricane Category Scale is based solely on wind speed and does not take into account other factors such as flooding from heavy rainfall. 

Types of Hurricane Categories

Within the Category Scale, hurricanes are classified into five levels of intensity. However, it is important to highlight that this classification is not the only way to understand the complexity of these phenomena. In addition to the Saffir-Simpson Scale, there are other systems that focus on specific aspects of hurricanes. 

Here we will explore some of the most relevant types of hurricane categories:

1. Categories by Size and Geographic Extension

Hurricanes can range in size from those with a compact core to those with a broad wind field. This classification considers the total area of hurricane winds and can provide a more accurate idea of how extensive a hurricane's impact can be in a region.

2. Categories by Precipitation

This approach focuses on the amount of rain that a hurricane can generate. Some hurricanes can bring torrential rains, resulting in catastrophic flooding. Classifying hurricanes by their precipitation potential can be critical to flash flood preparedness and response.

3. Categories by Travel Speed

The speed at which a hurricane moves can influence its impact. Slower hurricanes have more time to dump heavy rain on a region, increasing the risk of flooding. Classifying hurricanes according to their speed of movement allows authorities to more accurately forecast the associated risks.

Preparations by Category

Proper preparation for a hurricane varies according to its category on the Saffir-Simpson Scale. The higher the category, the greater the risks and the need for more stringent precautionary measures. Here is a basic guide to preparations based on hurricane category:

Category 1 and 2: Basic Preparation

  • Secure essential supplies like drinking water, non-perishable food, and medicines.
  • Reinforce windows and doors.
  • Establish an evacuation plan if necessary.
  • Keep electronic devices charged and radios powered in case of power outages.

Category 3 and 4: Advanced Preparation

  • Follow evacuation orders issued by authorities.
  • Reinforces structures and roofs.
  • Stock enough water and food for several days.
  • Prepare a first aid and medical supply kit.
  • Protect important documents in waterproof bags.

Category 5: Extreme Preparation

  • Evacuate following the instructions of local authorities.
  • Reinforce houses significantly or consider safer havens.
  • Stock up on supplies for at least a week.
  • Stay informed through radios and official channels.
  • Stay calm and follow established security protocols.

By understanding the hurricane categories and being prepared for each level of intensity, you can take proactive steps to protect your family, home, and community in the event of a weather event.

Resources and Advice

In times of hurricane threat, it is essential to have reliable resources and access to professional advice. Here are some key sources of information and services that can be of great help:

Governmental agencies

Weather and emergency management agencies provide up-to-date information on forecasts and warnings. In Puerto Rico, the State Agency for Emergency Management and Disaster Administration (AEMEAD) is the main entity that coordinates hurricane preparedness and response.

Mobile Applications and Websites

Numerous apps and websites provide forecasts, storm tracking, and preparedness tips. Some popular options include reputable weather forecast apps and hurricane websites.


Keep your radios and televisions tuned to local and national stations for updates and alerts. Many media outlets also offer information online and through social networks.

Disaster Response Organizations

Organizations such as the Red Cross and other disaster relief NGOs can provide emergency assistance, shelter and basic supplies.
